Replacement of rings on a gasoline walk -behind. Rings replacement on the Lifan motoroblock

Installation of piston rings on one.time tractor

In the process of soil processing, special mills participate. working bodies that directly carry out loosening. Another important element is a couch that allows you to configure the depth of processing. As a rule, the restriction of the council reaches 25 cm. Understanding how the unoic tractor plows will optimally regulate the level at which land cultivation will be performed. Rotating knives are driven by a drive mechanism, which can be different. with a diesel engine, gasoline or even electric. Such a system can be called automatic, however, considerable responsibility for the quality of work is also assigned to the user, who not only makes the primary settings of the mechanisms and regulates the parameters of plowing, but also controls the walk.behind tractor during loosening.

Often repair of a motor block engine is needed due to the fact that this motor is not started. If such a problem occurs after winter storage, you can suspect:

• clogging fuel or oil with water;
• oxidation of electrical contacts;
• insulation damage;
• The appearance of solid garbage in the carburetor.

To prevent these violations, you need to carefully examine any compounds before each launch. Noticing the slightest clip of the cable, especially its twisting, you cannot start the engine.

Even until the very first start, it is necessary to evaluate whether there is enough oil in the crankcase. With a lack of it, the rapid destruction of the piston group is likely. In less than a second, the cylinders are covered with burrs.

In this case, a very serious repair will be required, and sometimes completely replaced damaged parts. Sometimes the instability in the functioning of the device is provoked by leaving the lubricant for the winter. If it is precisely for this reason, in the first few moments after starting from the exhaust pipe, puffs of white smoke will be lit. Immediately after this, the power plant stalls.

Diesel motoblocks may also not start due to a lack of oil. Only a few models are equipped with systems protecting from falling lubrication levels. Most people will have to monitor the serviceability of the walk.behind tractor on their own. It is also worth considering that failures arise due to the systematic use of inappropriate fuel. If ordinary recommendations do not give a special effect, you need to remove the candle and see if there are stains of oil.

Oil, especially soar, should be carefully cleaned. Then they must dry the candle. Drying is required and cylinder. A very simple technique is used as “drying”: repeated sharply pulling out the starter cable. The question often arises: what to do if the one.axic tractor does not start, while smoking black smoke.

Usually this manifestation shows that the engine is overflated by gasoline. It is also worth fearing damage to the piston group. If both assumptions are incorrect, you need to contact the service center. Further attempts to eliminate problems on their own can lead to aggravation of breakdown.

When the violations are associated with the absence of fuel in the working chamber, the candle will be dry.

• pour the previous fuel;
• thoroughly wash a gasoline or diesel tank;
• clean the air filter;
• clean the fuel hose and nozzles with a stream of compressed air;
• Add fresh fuel;
• After the opening of the fuel line, blow the channel located in the gas tank cover.

In some cases, the failure is due to the fact that gasoline got into the crankcase for oil. Check if this problem is necessary after any adjustment, the carburetor setup.

If the clogging of the lubricant fuel occurs constantly, you need to see the needle of the carburetor. It is likely that this knot has become a weak place. It is worth noting that sometimes the motor.block motor shoots into the muffler, and, perhaps, even with the flame.

The most likely reason is the incompleteness of fuel burning. It provokes:

When the same.based tractor does not want to act, interruptions in the ignition system must be sought thoughtfully and sequentially. Examine magneto, caps, candles and high.voltage wires.

The search is of paramount importance even minor pollution. If everything is clean, it is required to inspect the contacts of the ignition wires

Next, check the stability of the electrodes, measure the distances between them using a special probe.

The purpose of the piston rings

These details serve as a seal between the piston and the cylinder. They are responsible for performing 2 functions:

• They do not allow excess motor lubricants to descend into the compartment of the internal combustion, leaving a small layer of grease on the walls of the part. This makes an oil scrap ring.
• Make a hermetic combustion chamber and remove hot gases from the piston. This is a task for compression rings.

The first compression ring is smelted from reliable and durable material, which withstands large degrees of temperature, but does not expand much when heated. A special coating on parts reduces the percentage of friction and protects against corrosion. The shape of the ring is arched with an end gap. This is necessary so that after installation the spare part tightly presses the piston.

The second compression also fit tightly to the piston and helps to remove excessive grease. It does not come in contact with high temperatures, so it is made from less durable materials. Different structure of products is explained by different action.

The oil scrap ring is located below all. It removes excess oil and leaves a thin lubricant film, which reduces the strength of compression friction and extends their service life. Change of piston details will help to return the initial qualities to the motor.

How does it work?

To understand breakdowns and eliminate them, it is important to understand how everything works in a normal situation. Let us dwell on greater simplicity only on models with ICE. Two.stroke motor blocks used to meet, but now they are increasingly replaced by four.stroke analogues. Diesel devices are also gaining popularity. As for the transmission, it can be performed in three different versions.

The traditional approach involves the use of gear transmission. Despite the decent level of reliability, this device takes up a lot of space. The transfer of effort occurs using either a cone or cylinder. Light motoblocks are mainly equipped with a gear-cherve transmission. The typical principle of operation of the motoblock regulator contains:

The control unit acts on the basis of pneumatic or mechanical communication. “Pneumatics” means the presence of a peculiar wing responding to the speed of the air flow. Centrifugal options involve the placement of a special distribution shaft inside the crankcase. It is complemented by small weights and an easily moving rod. The thrust is made of wire, and the sensitivity of the spring determines how accurately the speed values ​​will be maintained.

The role of the gas distribution mechanism is to supply a mixture of fuel and air into the cylinder. But the same device also ensures the removal of waste gases. To influence the degree of compression, decompressor is used. Gasoline motors are necessarily equipped with carburetors responsible for the preparation of the fuel-air mixture. Regardless of the type of fuel, the starting device plays an important role.

Elimination of problems with launch

Often repair of a motor block engine is needed due to the fact that this motor is not started. If such a problem occurs after winter storage, you can suspect:

• clogging fuel or oil with water;
• oxidation of electrical contacts;
• insulation damage;

DIY Cascade repair

The malfunctions that can arise in the cascade motor block can be divided into several main categories, some of them are:

If you have a single cascade tractor, then when using this equipment you have problems with the engine with the course of a certain period of time. The Unoic Cascade Tractor Tractor Instructions for Repair, provides an excellent opportunity for the owner of this technique, repair the faults that have arisen as quickly as possible and correctly, taking into account all the available recommendations from the manufacturer.

Do not forget to follow the state of your technique

Fuel emissions

If an attempt to launch a single tractor failed, this means that there are malfunctions in the engine or launch system. To determine the source of the malfunction, first check the spark plugs.

If the spark plugs are dry, this means that the fuel mixture does not fall into the cylinders of the engine. There may be several reasons:

• There is no fuel in the tank;
• The fuel supply valve is closed;
• The hole in the riveted tanning rod is clogged;
• Extraneous objects fall into the fuel supply system.

To eliminate problems with the supply of fuel, you need:

• Fill out one.axle tank tractor.
• Open the fuel valve.
• Clean the drain hole in the tanning ropard.
• Remove the fuel valve, drain gasoline from the tank and rinse it with clean gasoline. Then remove the connecting hose located from the carburetor side, and blow it together with the carburetor’s nozzles, without disassembling the latter using the fuel pump.

Functional failures

Quite often, among the malfunctions of the engine of the walk.behind tractor, its unstable effect appears. If the motor at idle works with jerks, and when trying to add gas stops completely, the reason is rooted in a lack of fuel. The fuel tank nets, carburetor and pipeline crane should be cleaned. And when problems arise even at idle, it is advisable to check the centrifugal regulator. The craving often seals there.

Suppose the same.based tractor simply drops momentum without jerking. In many cases, this is due to the use of incorrect, inappropriate or simply strongly worn motors. But replacing the power plant is not always reasonable. The installation of a better ignition candle can help. It is also worth assuming the appearance of failures in the operation of a carburetor float in a high.voltage wire.

If the engine of the walk.behind tractor knocks, it is required to examine the distribution and crankshaft. It is there that the sources of extraneous sounds are mainly located.

In all these situations, there is no particular need to carry out major repairs. High.quality diagnosis of malfunctions is very important. Trying to increase compression in all modern motors is pointless, still the decompressor will not allow this to do this.

Tips

To repair and establish a single tractor less often, you need to protect the motor from the fall. This is especially true for products with four.stroke engines. Their maximum inclination during operation cannot exceed 25 degrees. For a long time to tilt the unit cannot be at all by more than 15 degrees. Otherwise you can fear that part of the engine will be devoid of lubrication. Soon she will fail.

For the same reason, long.term work of the walk.behind tractor in idle mode is not recommended. Before starting work, you should always check if there is enough fuel and lubricating oil. Change these liquids and even add them only with the motor disconnected.

You can not run the same tractor when the levers associated with the wheel drive are blocked. The cold motor is allowed only after installing the air shutters of the carburetors in a closed position; Always use strictly recommended fuel.

Valve adjustment is carried out using:

See the intricacies of the Subaru EX21 engine for the Neva walk.behind.

It is forbidden to use any materials without our preliminary written consent.

How to change the oil seal

Another important point in the repair of the walk.behind tract. This is a change in oil seal on the gearbox.

Therefore, first of all, it is worth studying the theoretical part, namely the parts that make up this knot.

The gearbox body consists of two halves. They are stamped from steel and fixed together with a rubber gasket for sealing and compaction. Steel corners are welded to the body, which, in fact, form the supporting frame of the entire device.

To perform all types of work in agricultural and construction sectors, special equipment is often required. All about the universal bulldozer T-13.

Many are used to putting potatoes manually, but having a tractor or off.road tractor in stock, you might think about making a potato gardener for potatoes. By clicking on the link, you will find out how to make a potato sled with your own hands.

In parallel by the output shaft and perpendicular to the gearbox body, which contains chains and bolts that hold it together. They, in turn, are installed on them, pins and bolts are installed, there is a block of switching lever. A chain of forty.six links leads to it.

The block itself consists of an input shaft, with which the transmission changes. There are also stars that are responsible for the first and second programs.

The displacement shaft, over time, can lead to a malfunction. The weak side in it has a switch-switch, which wears out over time, and the unoic tractor works, to put it mildly, unsatisfactory. Sooner or later it will have to be replaced, and for this you need to completely dismantle the gearbox.

In order to replace the cuff on the gearbox of the Prika Prikantor, such manipulations are not needed. Having sufficient skill and knowledge of design features, everything can be done without analyzing anything.

• It is enough to easily remove the trunk and sleeve, the oil seal can be removed using a screwdriver.
• Next, you just need to replace the old cuff, carefully putting it with a hammer, install a sleeve and trunk.
• If you have no experience with removing something using a screwdriver and a hammer, in this case it is better to remove and disassemble the gearbox. just remove its body.

How to put an ignition correctly

The operation of any device begins with the start of the engine, and the ignition system should work no worse than the Swiss watches.

Before that, how to install ignitions on the pedestrian tractor Luch, Don, Hater, Pro, Lander, Champion, which is needed, first of all:

• Check the candles. They are the main reason for the refusal of this system. It is also always recommended to have a spare candle, if manipulations, cleaning do not help. To deal with fire, you need to turn it off and wipe the electrodes and remove carbon deposits from them.
• Next, you need to install the gap between them.
• Then put the square of the wire on the candle and reliably press its body to the cylinder, its chairman, while distracting it from the hole that is in the cylinder head.
• You need to return the crankshaft. You can cope with this cord with this. In the working system, a spark that slides between the electrodes should be light blue in color. If it is absent or has white and yellow, the system is faulty.

In this case, you can check the gap between the stator and flywheel of the flywheel, it should be from 0.1 to 0.15 millimeters.

After these simple manipulations, you will receive a perfectly working one.based “ray” tractor. It is also easy to install ignitions on it, as well as its settings, since it consists of several parts that are connected as parts of the designer.

All grooves are made in such a way that nothing can be confused, inserted a candle from the wrong side or incorrectly connect the wires. After you adjusted the ignition of the RAY motor block, and this part of it works properly, you can start setting up the next important engine unit.

How to replace the piston rings-auto-plus-sales Motrac, tractor, motoblok, sparter

The emergence of characteristic signs of engine malfunctions, such as a sharp deterioration in the dynamics, increase in fuel consumption and engine oil, problems with the start of the engine, especially in the cold season, suggests that the wear of the power unit has reached the limit, and without extraneous intervention, further operation of the machine is impossible. The listed signs indicate a sharp drop in compression. If the motor is not “Ushatan” completely, then to return to it vigor, most likely, the replacement of piston rings will help.

In order to save replacement, you can do it with your own hands. In addition to financial benefit, the owner of the car may be absolutely sure that the piston rings are changed, and it is for those that he bought, and the work was done efficiently. Unfortunately, leaving the car in a car service, the owner cannot know exactly how conscientiously the masters have done their work, since statistics stubbornly repeat that they are deceiving everywhere, including on official services.

About how to replace piston rings with your own hands, is written in this article.

• the head of the cylinder block is dismantled;
• The condition of the rings is checked and the issue of the need to remove the motor from the car is resolved;
• then the old ones change to new ones, and the engine is assembled in the reverse order.

Further, each stage will be considered in more detail.

Before putting new rings

Before starting work, you need to get everything necessary. For the operation, you will require worships, heads, preferably, with ratchet, a dynamometric key and piston roller puller.

When choosing a new set in the auto parts store, you should pay attention to both the appearance of the packaging and the rings themselves.

The packaging should have complete information about them, namely: who is the manufacturer, what are made of and t. P. There should also be a marking indicating the upper side on the rings, they themselves should not have any flaws, in addition, there should be instructions on the packaging or inside, which describes the correct installation of piston rings.

If the seller claims that small defects will fit. he frankly lies, trying to scoop the non.documentary goods, it is better to refuse such a purchase, since the money will be wasted.

Preparatory stage

First of all, you need to turn off the battery. After that, you need to drain the coolant from the cooling system and motor oil from the crankcase pallet. Replacing piston rings is possible in two ways: with the removal of the engine from the car and without. Determine whether it is necessary to remove the motor, the check will help: it is necessary to remove the cylinder head and visually evaluate the condition of the sleeve.

If signs of wear are visible on the walls of the cylinders (production, any scratches or bullying), the power unit will definitely have to be removed to waste the sleeves for the next repair size. If this is not done, there will simply be few to change the rings, since they will quickly become unusable due to damaged cylinders.

If there is no production, new ones can be placed without removing the motor from the car. The stages of work on replacing piston rings, with the exception of the engine dismantling for restoration work, the same.

Replacing piston rings

The replacement process begins with the dismantling of the Carter pallet. It is advisable to remove the oil pump and check how much it is worn out. Then you need to unscrew the lids of the connecting rods and push the connecting rods with the pistons up. It is important to remember that the lids of the connecting rods cannot be changed, each subsequently must be screwed to their connecting rod.

The next stage is directly, replacing the piston rings. The easiest way is to replace if there is a piston rifle puller. It is a forceps, unclenching rings.

The main thing is not to overdo it and not to unclench too much, since they can simply break. If there is nowhere to take the device for installing piston rings, you can get by with a thin screwdriver with a flat sting.

The task, of course, will become more complicated, but you can cope with it. It is necessary to put them with caution so as not to scratch the pistons with a screwdriver.

Checking the condition of the removed rings will identify cylinders deformation. Uneven wear of piston rings suggests that during operation the cylinders took an oval form in the cross section. In this case, it is advisable to waste them, since the new spare parts will wear hard, and after replacing them will not be enough for a long time. You can change to drive for some time, but overhaul, nevertheless you will have to produce in the near future.

After removing the old rings, you need to remove the carpet out of the grooves, which will prevent the installation of a new set. The perfect gun for this procedure is a fragment of an old ring, so one of them needs to be broken. Also, soot must be cleaned from the bottom of the pistons if it is there. To facilitate the task, you can moisten the surface with kerosene. Act, again, you need to carefully do not leave scratches.

The installation procedure is as follows: the oil.spleen ring is first installed, then the second and first compression. Due to the fact that the second compression and oil-shooting rings work in less difficult conditions than the first compression, to the metal from which they are made, less stringent requirements are made, so the rings are more fragile. When installing them, special care should be shown. It is almost impossible to break the first compression ring inadvertently.

When installing, you should pay attention to the location of the locks of piston rings: they should not be located in one fishing line for a trimmer. It is best to place the castle of each next at an angle of 120 degrees with respect to the previous. The correct location of the piston rings additionally prevents the breakthrough of the gases from the combustion chamber into the crankcase.

The next responsible stage of work is the installation of the piston back to the cylinders. To put the pistons in place, it will require a mandrel for piston rings, otherwise they will prevent the piston entrance to the cylinders.

It can be as universal, designed for pistons of different diameters from 50 to 150 mm, or specially made for a specific size.

Using this device, piston rings are squeezed, after which the piston is driven into the cylinder greased with motor oil by accurate tapping along the bottom with some non-metallic object.

Motoboblock engine Cascade Video Repair. Together Making Making

The problems of the walk.behind tractor can be divided into two types: malfunctions of the motor and problems with different mechanisms and nodes. If you have such equipment, then there is a high probability that during use you may encounter any engine problem. The instructions for repairing the Cascade motornote, given in the article, will help you understand what problems could have arisen in the engine, and also how to eliminate them.

Motor malfunctions

The problems of the motor may indicate a spontaneous stop, lack of power levels and interruptions:

• If a gasoline engine is delivered in the unit, then in the process of finding problems you need to check if there is fuel in the tank, what is the state of the special damper of the device, how the ignition is performed, whether fuel goes to the carburetor.
• To check the final condition, you need to fill out a special camera, using one button. In this case, the fuel should be poured out of the hole in the lid of this chamber. If gasoline acts with a small stream or it is not visible at all, it may be the problem of contamination of the fuel filter or clogging of the valve of the device. In this case, the recommendation for the repair of this walk.behind tractor advises to clean the valve or filter.

Fuel passage problems

The fact that the fuel enters the motor cylinder may indicate the condition of the candle. It must be checked by twisting the cylinder from the lid, connecting the wire in advance. If the candle is dry, then this means that the fuel does not get into the cylinder. If you managed to find out that it goes to the carburetor, then the main reason for the engine failure of the launch may be the clogging of the device of the device filter.

Sometimes the clogging of the nozzles leads to serious problems. Subject to all conditions, the instructions for repairing the walk.behind tractor provides for the possibility of removing the carburetor, disassembling and cleansing the part. These manipulations can be performed without visiting the master.

Checking the condition of the candle

The recommendation for the repair of the unit, which you must be studied before the work, will help you realize how to carry out the inspection of the condition of the candle. If it is wet, then gasoline goes into the cylinder. Refusal to launch may be due to an excess of a special mixture.

If the surface of the candle is strongly covered with gasoline, you need to dry the cylinders, pump the engine with a starter, leaving the candle in a well.twisted state.

Before this manipulation, the master should close the fuel supply. The candle may be clogged with a soil, while it is cleaned with a small skin and gasoline. The main thing is to analyze what value the gap between the electrodes will have. If necessary, then it is worth adjusting, following the rules submitted by the manufacturer in the instructions. The size of the clearance should be 0.8 mm.

Problems with the ignition system

The ignition of such a device can also fail. If this is what happens, you need to check the condition of the candle, clean it and start adjusting the gap. In parallel with this, you will have to analyze if there are breakdowns in the electrical circuit. The master should see what gap is preserved between the magnetic circuit and the coil. Different models of the selected manufacturer have recommendations for such work, and they are indicated in the instructions.

Problems with a carburetor

The carburetor of the walk.behind tractor can be contaminated, in many cases it may be adjusted incorrectly. If this happens, then such a node is removed and cleaned, its adjustment is performed, which should be provided for by the rules:

Another problem may arise, which is expressed in the fact that the air into the carburetor is incomplete. This can turn out due to clogging of the air filter, ultimately the fuel mixture comes out of the reinforced.

Depending on the material at the base, it is necessary to save the part of the dirt in one of the effective ways. If the carburetor of the device began to receive air in small quantities, then it may be necessary to clean the paper filter, which is done with a slight tapping or blowing.

So you learned how to carry out repair of the Cascade motornote.

Motoblocks “Cascade” have established themselves from the best side. But even these reliable and unpretentious devices sometimes fail. It is very important for owners to determine the causes of the failure, to figure out whether it will be possible to solve the problem on their own or not.

The block does not work or works unstable

It is logical to start the analysis of possible breakdowns with this situation: the cascade unoic tractor starts and immediately stalls. Or completely stopped starting. The following reasons are most likely:

• excess gasoline (the moisture of the candle speaks of it);
• In models with an electric starter, the problem often lies in the discharge of the battery;
• The total power of the motor is insufficient;
• a failure arose in a silencer.

Replacing piston rings

After dismantling the pistons, using connecting rods, you can start removing old rings. To do this, you can use a special device or just carefully break them, avoiding damage to the piston with all this. Shards of rings can be used to remove carbon deposits and deposits from the channel for the seat. If this is not done, then new rings may simply not fit.

The acquisition of new rings should be treated with special attention. The sets of rings of the usual properties should be recommended by the company, painstakingly packaged and will be short control for labeling and installation. If the acquired rings are simply twisted into a sheet of paper, then you do not have to read about the quality of such spare parts.

Then you can start installing new rings. It is very fundamentally observed when installing. Always at first put on an oil scraping ring, then. Compression. It is also purposeful to observe the provisions of the ring in the up and down relationships. If there are special latches in the piston grooves, you should adhere to uniformly clearance of locks throughout the circumference.

, In the piston with 3 compression rings, the locks should be at a distance of 100 20 from each other. All appropriate sequences and order can be seen on the marking of the rings and on the instructions from the manufacturer.

Also, true geometry of rings can often be excited without the use of the device. This means that when using a very large force, the ring is installed, it becomes rounded. At the same time, he completely loses the characteristics of a dense fit to the cylinder liner. The results of such repairs can be an empty embezzlement of time.

Dismantling of the piston system

To replace the rings in any case, it will be necessary to disassemble the engine for you. There are two options: either disassemble it in place, or dismantle it from the car. In any case, you should start removing the lid of the gas.shaped mechanism and dismantle the cylinder head. Already at this step it will become clear, to change the rings on the installed engine, to remove it absolutely.

, and there are no significant production on them, then you can limit yourself to the substitution of the rings.

Engine malfunctions

If we are talking about a gasoline engine, when looking for a malfunction, it is necessary to sequentially check all the possible causes of problems, namely:

The state of the candle, which in any case, must be checked when searching for faults in the ignition system may indicate about the intake of the engine. The candle is twisted from the lid of the cylinder, having previously disconnected the wire, and inspected. If it is dry, this means that the fuel mixture is not supplied to the cylinder. And if it was established before that that gasoline enters the carburetor, then the cause of non.inflammation of the engine can be in the carburetor. pollution of its mesh-filter, clogging a nozzle or some other malfunction. Whatever this, the carburetor must be removed, disassembled and cleaned, but this device is very complex and before its repair it should at least see the carburetor circuit.

Wet candle say that fuel enters the cylinder. Sometimes the unoic tractor does not start from an excess of the fuel mixture, so if there is too much gasoline on the candle, you need to dry the cylinder, well “pumping” the engine with a hand starter with a turned candle. Before that, you need to block the fuel supply.

If the candle is contaminated with a breed, it should be cleaned with gasoline and small skin. It is also necessary to check the size of the gap between the electrodes and, if necessary, adjust it in accordance with the requirements of the operating manual. Typically, the gap should be about 0.8 mm.

After that, it is necessary to check the presence of a spark. attach the wire to the candle, press its metal part to the cylinder cover and simulate the starter of the engine by the starter. If the candle is working, there will be a spark between the electrodes. Sometimes it happens that the spark arises, but so weak that it is not enough to ignite the fuel. If there are doubts about the power of the spark, you need to check the operation of the engine with a new candle.

The absence of a spark may mean a candle malfunction, lack of contact in an electrical circuit, a violation of the gap between the ignition coil and the magnetic circuit, the ignition of the ignition coil failure. All these elements must be checked. Faulty candles and ignition coil must be replaced.

In the event that the uniform tractor is equipped with an electric starter, the engine may not start due to the discharge of the battery, fuse burning out, and starter malfunctions. It is necessary to check the battery charging, replace the fuse, repair or replace the starter.

If the engine of the walk.behind tractor starts, but does not develop power (works with interruptions, stalls or does not gain speed under load), the following malfunctions may be possible causes of unsatisfactory work.

The air filter is contaminated, as a result of which the air enters the carburetor in insufficient quantities, and the fuel mixture is re.enriched. Proper maintenance of a walk.behind tractor involves periodic air filter cleaning, however, with very dusty operation, more frequent cleaning may be required. You need to check the condition of the air filter and, depending on its material, clean in one of the right methods. The paper filter is cleaned with light tapping about something solid and blowing with a vacuum cleaner, foam rubber is washed in water with a detergent and dried, mesh is blown with a vacuum cleaner, etc.D. When developing the operating life, filters must be changed.

Motobobok engine malfunctions: We solve the problem on our own

Like any technique of one.time tractor requires timely maintenance and repair. And it is advisable to entrust their implementation to specialists who have the right tools and equipment and know their job well. However, if you are also familiar with the device of internal combustion engines and understand the topic in mechanical engineering, then a lot of what may be required to restore the performance of the machine, you can do it yourself.

To obtain additional information, which can be useful during the repair of the tractor, see. The structure of the tractor.

Engine malfunction

If we are talking about a gasoline engine, then when eliminating malfunctions, it is necessary to sequentially check all the possible reasons for the refusal, namely:

The state of the spark plug, which in any case must be checked when searching for faults in the ignition system, may indicate the fuel flow into the engine cylinder. The candle is unscrewed from the lid of the cylinder, having previously disconnected the wire and examined. If it is dry, this means that the fuel mixture is not supplied to the cylinder. And if it was previously determined that gas enters the carburetor, then the carburetor may be the cause of the engine. pollution of its filter mesh, clogging of nozzles or other malfunctions. Be that as it may, the carburetor must be removed, disassembled and cleaned, but this device is very complex, and at least it is worth checking its carburetor chain before repairing it.

Wet candle indicates that fuel enters the cylinder. Sometimes the engine block does not start due to an excess of the fuel mixture, therefore, if there is too much gasoline on the spark plug, it is necessary to dry the cylinder, carefully pumping the engine with a hand starter with a removed light of the ignition. Before that, fuel supply should be disconnected.

If the soot is polluted by soot, it should be cleaned with gasoline and thin sandpaper. You should also check the gap between the electrodes and, if necessary, adjust it in accordance with the instructions. Typically, the gap should be approximately 0.8 mm.

Then you need to check for a spark. Connect the wire to the spark plug, press the metal part of the spark plug to the cylinder cover and simulate the engine starting from the starter. If the spark plug works, a spark will appear between the electrodes. Sometimes a spark arises, but it is so weak that it is not enough to light the fuel. If you doubt the power of the spark, you need to check the engine with a new spark plug.

The absence of a spark may indicate a malfunction of the spark plug, lack of contact in the electric circuit, rupture in the gap between the ignition coil and a magnetic chain, the failure of the electronic ignition coil. All these items must be checked. Faulty spark plug and ignition coil should be replaced.

If the motor unit is equipped with an electric starter, the engine may not start due to a low charge of the battery, a burned fuse or the starter malfunction. Check the battery charge, replace the fuse, repair or replace the starter.

If the engine unit starts, but does not develop power (interrupts, stops or rotates under load), possible malfunctions can lead to a decrease in performance.

The air filter is contaminated, which leads to an insufficient amount of air entering the carburetor and re.enriching the fuel mixture. Proper maintenance of the motor unit requires periodic cleaning of the air filter, however, with very careful work, more frequent cleaning may be required. It is necessary to check the condition of the air filter and, depending on its material, cleanse it in one of the suitable methods. The paper filter is cleaned, slightly pressing on something solid and blowing a vacuum cleaner, the foam is washed with water with a detergent and dried, the mesh is blown with a vacuum cleaner, etc.P. When developing, the service life of the filter must be changed.

Earth cultivation

The purpose of Lifan motor cultivators is a high.quality cultivation of land for planting, caring for seedlings and harvesting. This type of technique is great for processing areas of medium and small area with any relief and various types of soil. The land plowing on this unit is available to a depth of 200 mm, which allows only a fertile soil layer to dig out, leaving more deep clay layers untouched.

Thanks to the large selection of attaching equipment using the Lifan walk.behind tractor, any kind of personal work can be done depending on the season and needs of the consumer. Changing the components of the motor.cultivator can be used all year round, starting with plowing and landing, and ending with snow cleaning in the winter.

The standard equipment of the walk.behind tract includes:

• Cutters.
• D350 mm wheels for a walk.behind tractor.

• Plow.
• Hayfield.
• Potato.cap.
• Pump equipment.
• Snow removal equipment and others.

Lifan engine power in recent models allows you to easily treat virgin lands with complex mixed soil. However, when working with a motor.cultivator, do not forget about the need to maintain technology maintenance.

Tips

To repair and establish a single tractor less often, you need to protect the motor from the fall. This is especially true for products with four.stroke engines. Their maximum inclination during operation cannot exceed 25 degrees. For a long time to tilt the unit cannot be at all by more than 15 degrees. Otherwise you can fear that part of the engine will be devoid of lubrication. Soon she will fail.

For the same reason, long.term work of the walk.behind tractor in idle mode is not recommended. Before starting work, you should always check if there is enough fuel and lubricating oil. Change these liquids and even add them only with the motor disconnected.

You can not run the same tractor when the levers associated with the wheel drive are blocked. The cold motor is allowed only after installing the air shutters of the carburetors in a closed position; Always use strictly recommended fuel.

Valve adjustment is carried out using:
